Problems solved by technology

The clinical application of breviscapine is mainly small injections. Clinical application has proved that the effect of small doses of breviscapine is not good, and only large doses (20-40ml or even larger) can be effective. Clinical application requires many small needles to be sawed open and poured. into normal saline or glucose injection, troublesome operation and easy to cause pollution
At the same time, it was also found that the small needle preparation of breviscapine had problems of poor stability and clarity

Abstract

The Breviscapine infusion preparation is compounded with Breviscapine as main component, glucose or sodium chloride, propylene glycol, L-arginine, sodium bisulphate, EDTA-2Na and water for injection through certain technological process. The preparation is suitable for great dosage application clinically to avoid cross infection caused by intermediate links. In addition, the present invention is clear and stable.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to an intravenous infusion preparation with breviscapine as the main component and a preparation method thereof, specifically breviscapine glucose injection and breviscapine sodium chloride injection and a preparation method thereof. Background technique [0002] Breviscapus is a total flavonoid extracted from the plant Erigron breviscapus (Vaniot) Hand Mazz of Compositae, mainly used in the treatment of cardiovascular and cerebrovascular diseases. At present, it is widely used in clinical practice with definite curative effect, and the total effective rate is more than 90% for coronary heart disease, angina pectoris, cerebral thrombosis, paralysis caused by cerebral infarction and other diseases. The clinical application of breviscapine is mainly small injections. Clinical application has proved that the effect of small doses of breviscapine is not good, and only large ...
